HEATINGDRUM.

SPECIFICATION forming part of'Lette'rs Patent No. 652,604, dated June26, 1900. Appunti@ med March 7, i900. serial No. 7.679. (No man.)

To @ZZ whom t may concern:

Be it known that I, CHARLES. H. EVELAND, acitizen of the United States,and a resident of Philadelphia., Philadelphia county, State ofPennsylvania, have invented certain new and useful Improvements inHeating-Drums; and my preferred manner of carrying out the invention isset forth in the following full, clear, and exact description,terminating with claims particularly specifying the novelty.

This invention relates to stoves and furnaces,and more especially tothat class thereof known as lamp-stoves 5 and the object of the same isto produce an improved heating-drum adapted to be suspended over a lampor gasjet in such manner as not to interfere with the light given out bythe same, but to the end that the heat rising from the flame will becaught by the drum and radiated for the purpose of warming the room.

The invention consists,essentially,in a base and cover connected by abolt,which may form part of the supporting means, and a cylinder heldbetween said base and cover by the bolt and preferably having inlet andoutlet. In the following specification several modifications of andadditions to this main idea are set forth, all as illustrated in theaccompanying drawings, wherein- Figure l is a general side elevation ofmy drinn supported by a bracket above a lamp. Fig. 2 is a sectional viewof the drum, showing a coil surrounding the bolt. Fig. 3 shows inperspective a detail of several of the parts disconnected. Fig. et is asection showing the use of a casing to surround the cylinder andomitting the coil. Fig. 5 is a section similar to Fig. 4l, except thatthe cylinder is shorter than the casing and has a cover of its own. Fig.6 is a detail of a bolt of slightly-modified construction.

In the said drawings the numeral l designates a base, which may well beof light castiron and whose bodyis concavo-convex, while its center ispierced with an opening` 2, sury rounded by an upright iiange 3.

4t is the cylinder, which may well be of polished copper, brass, orother sheet metal, of a size at its lower end to lit around the flangeand preferably tapering slightly toward its upper end.

Gis the cover, of a size to close said upper end of the cylinder,preferably depressed slightly at its center, as at 7, and alsopreferably having a surrounding depressed llange S.

l0 is the bottom, which may well be a plate of metal of a size to iitwithin the base and larger than the opening 2, so that the latter willbe closedithereby.

12 is a boltextending longitudinally through the cylinder 4 andconnecting the cover 6 with the bottom lO. The latter is usually piercedwith inlet-openings 1l, whereby the heat rising from the flame andcollected by the base passes upward into the cylinder. In some cases, asin Fig. l, I provide no`outlet-open rings, and the heat is thereforeforced to ac cumulate within the cylinder and radiate laterallytherefrom, while the escaping produ cts of combustion pass out certainof the openings ll. In solne cases, asin Figs. 2 and 3, I

make the cover corrugated, as indicated at 9,

'may be employed, and I have shown two in the accompanying drawings. AThe bolt 12 may be an eyebolt, with its eye 2O .above the cover and itsnut 2l beneath the bottom, as best seen in Fig. 4. As seen in Fig. 6,the eye could be replaced by a hook 200, and thel shank of the boltcould be threaded to receive additional nuts 210, adapted for use inconnection with Fig. 5, as explained below. If the parts were notintended to be removable, the bolt might be replaced by a rivet,`andobviously there could be a plurality of these bolts or rivets. In Fig. 2a spring-handle is shown, consisting of a wire coiled, as at 25, withits ends 26 extending downward and having their extremities 27 bentinwardin the form of hooks removably engaging holes 28 IOO eyebolt abovedescribed or with a rivet or other means for holding the cover and bot,-tom rigidly connected. In Fig. 1 is shown one form of bracket 29, havinga hook for supporting the drum. However, my device may be suspended inany suitable manner over the flame of a lamp or gas-jet. A coil 30, asof copper wire, may surround the bolt or rivet (or each of them) betweenthe cover and the bottom, its function being to collect and retain to acertain extent the heat within the drum and to radiate it outward to thecylinder, which latter in turn radiates the heat outward into the room.By ceiling this wire its expansion and contraction are permitted withoutthe noise so often'resulting in devices of this character. The boltitself might also be ofcopper or other material which is a goodconductor of heat. I do not wish to be limited to the specific materialof which any part is composed.

I In Figs. 4 and 5 is shown a casing 50, surrounding the cylinder and ofsuch interior diameter as to leave a space between them. This casingpreferably rests at its lower end upon the base l and is providedadjacent the same with outlet-openings 5l, the inlets to said spacebetween the casing and cylinder consisting of the outlets 5 of the.latter. In Fig. 4 the upper end of the casing is clamped beneath t-hecover G, which is made sufliciently large for this purpose. In Fig. 5there is a supplemental cover 60, standing above the vcover 6 of thecylinder, which latter is here shorter than the casing, as shown, andthe covers may be held upon their parts by the nuts 210 of Fig. 6 or inany other suitable way. In the use of my drum when provided with thiscasing the heat enters the inlet at the bottom of the cylinder, ascendswithin the same, and passes out its outlet whatever the form ot' thelatter. Then entering the casing at its upper end it descends thereinandl passes out the outlets 5l at the lower end. Itis obvious that acoil of conductive material may be employed in this connection, ifdesired, and it is also obvious that the specie form of support to beused herewith is susceptible of considerable variation.

What is claimed as new is- 1. A heating-drum comprising a concaveconvexbase with a central opening, a flange on the convex side, a perforatedbottom larger than said opening and closing it from the concave side, acover, a cylinder extending from the base around said flange to thecover,

outlets adjacent the latter, and a bolt extending ythr-oughout thecylinder and passing through the bottomand cover, as and for the purposeset forth.

2. A heating-drum comprising a concaveconvex base with a central openingsurrounded by a llange on the convex side, a perforated bottom closingsaid opening from the concave side, a cover, a cylinder extending fromaround said flange to the cover and having outlets adjacent the latter,connections between said bottom and cover extending throughout thecylinder, and supporting devices, all as and for the purpose set forth.

3. Ina heating-drum, the combination with a base having a centralopening surrounded by an upturned ange, a perforated bottom platebeneath the base and larger than said opening,` a cylinder rising fromthe base around the flange and having outlets near its upper end, andsupporting devices connected with said bottom and extending through thecylinder; of a covered casing surrounding the cylinder and resting atits lower end on the base, outlets therefrom near said lower end, andconnections between its cover and said supporting devices, as and forthe purpose set forth.

4. In a heating-drum, the combinationwith a base having a centralopening, a perforated bottom plate beneath the base and larger than saidopening, and a cylinder rising from the base and having outlets nearits-upper end; of a casing surrounding the cylinder and resting on thebase, perforations in the casing near its lower end, a cover closing itsupper end, and supporting devices extending from the plate throughoutthe cylinder and through the cover, as and for the purpose set forth.

5. In a heating-drum, the combination with a base having a centralopening, a perforated bottom plate beneath the base and larger than saidopening, a cylinder rising from the base and having outlets near itsupper end, and a cover for said upper end; of a casing surrounding thecylinder and resting on the base, perforations in the casing near itslower end, a cover closing its upper end above that of the cylinder, anda bolt passing through both covers and the plate and having nutsadjacent all these parts, as and for the purpose set forth.

In testimony whereof I have hereunto subscribed my signature this 3d dayof March,

CHARLES H. EVELAND. Witnesses:
